Hybrid tea rose plant named &#39;meigoudea&#39;

ABSTRACT

A new and distinct Hybrid Tea rose plant is provided which abundantly forms attractive mildly fragrant very double blossoms that are coral pink in coloration. The growth habit is tall and bushy. Vigorous dense dark green semi-glossy foliage is displayed that contrasts well with the coral pink blossom coloration. The plant is particularly well suited for providing attractive ornamentation in the landscape.

BOTANICAL/COMMERCIAL CLASSIFICATION

Rosa hybrida/Hybrid Tea Rose Plant

VARIETAL DENOMINATION

cv. Meigoudea

SUMMARY OF THE INVENTION

The new Hybrid Tea rose plant was created by artificial pollination wherein two parents were crossed which previously had been studied in the hope that they would contribute the desired characteristics. The female parent (i.e., the seed parent) of the new variety was the product of the controlled cross of the ‘Emily Post’ variety (U.S. Plant Pat. No. 3,749) and the ‘Korlift’ variety (non-patented in the United States). The ‘Emily Post’ variety sometimes is known as the ‘Omega’ variety and the ‘Korlift’ variety sometimes is known as the ‘Sylvia’ variety. The male parent (i.e., the pollen parent) was the product of the controlled cross of the ‘Merkor’ variety (U.S. Plant Pat. No. 3,724) and the ‘Prima Ballerina’ variety (non-patented in the United States). The parentage of the new variety can be summarized as follows:

(‘Emily Post’×‘Korlift’)×(‘Merkor’×‘Prima Ballerina’).

The seeds resulting from the pollination were sown and small plants were obtained which were physically and biologically different from each other. Selective study resulted in the identification of a single plant of the new variety.

It was found that the Hybrid Tea new rose plant of the present invention displays the following combination of characteristics:

-   -   (a) exhibits a tall and bushy growth habit,     -   (b) abundantly forms attractive mildly fragrant very double         blossoms that are coral pink in coloration,     -   (c) forms vigorous dense dark green semi-glossy foliage that         contrasts well with the coral pink blossom coloration, and     -   (d) is particularly well suited for providing attractive         ornamentation in the landscape.

The new variety well meets the needs of the horticultural industry and can be grown to advantage in parks and gardens where attractive ornamentation is desired. Good tolerance with respect to Powdery Mildew and Black Spot has been observed.

The new variety of the present invention readily can be readily distinguished from its ancestors. For instance, the ‘Emily Post’ variety displays soft medium pink strongly fragrant flowers. The flowers of the ‘Korlift’ variety are pink with a high center and are not fully double. The flowers of the ‘Merkor’ variety are orange-red in coloration and the blooms of the ‘Prima Ballerina’ variety are hot pink in coloration with a high center.

The new variety of the present invention also can be readily distinguished from other similar Hybrid Tea varieties such as the ‘Meisocrat’ variety (U.S. Plant Pat. No. 9,613) and the ‘Meikarouz’ variety (U.S. Plant Pat. No. 14,039). The blooms of the ‘Meisocrat’ variety are true pink in coloration, and those of the ‘Meikarouz’ variety are deep red in coloration.

The new variety has been found to undergo asexual propagation in the South of France and at Wasco, Calif., U.S.A., by a number of routes, including budding, grafting, and by the use of cuttings. Asexual propagation by the above-mentioned techniques at such locations has shown that the characteristics of the new variety are firmly fixed and are stably transmitted by such asexual propagation from one generation to another. Accordingly, the new variety asexually reproduces in a true to type manner.

The new variety has been named ‘Meigoudea’.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph shows, as nearly true as it is reasonably possible to make the same in a color illustration of this character, a typical specimen of the new variety. The rose plant of the new variety was approximately two years of age and was photographed during June while growing outdoors on Rosa froebelli understock near West Grove, Pa., U.S.A.

FIG. 1 illustrates the typical very double coral pink flowers, buds, and dark green semi-glossy foliage of the new variety.

DETAILED DESCRIPTION

The chart used in the identification of the colors is that of The Royal Horticultural Society (R.H.S. Colour Chart), London, England. The description is based on the observation of two-year-old plants during June while growing outdoors on Rosa froebelli understock near West Grove, Pa., U.S.A. Color information in common terms sometimes is provided. Such terminology is to be accorded its ordinary dictionary significance.

Plants of the ‘Meigoudea’ variety have not been observed under all possible environmental conditions to date. Accordingly, it is possible that the phenotypic expression may vary somewhat with changes in light intensity and duration, cultural practices, and other environmental conditions without variance in the genotype.
